All the recent support of Creative boards and onboard audio depend on PCI, but they can't be trimmed easily even if you build without CONFIG_PCI, since the quirk is detected dynamically and the code has many branches with the flag check like spec->quirk type or spec->use_alt_functions. This patch makes these checks static for CONFIG_PCI=n case so that the compiler optimizes out. The access to flags are replaced with macros that are replaced with a static value for CONFIG_PCI=n. The macros look slightly ugly for avoiding compiler warnings wrt unused variables, and some additional default-case handlings for another compiler warnings, but the rest are very straightforward changes.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
